摘要

Animal behavior is the link between organisms and their environment and is critical for biological adaptation. Despite many studies demonstrating the sensitivity and utility of behavioral endpoints in bioassays assessing potential pollutant effects in aquatic ecosystems, behavioral toxicity testing has not, historically, been included routinely in assessments of aquatic toxicity and subsequent environmental policy formulation. The results of behavioral risk assessments may allow behavioral toxicologists to demonstrate that a chemical is not merely a potential hazard, but that it elicits a functional change in an animal. In this regard, the behavioral toxicologist is on stronger ground than toxicologists recommending action based on isolated, non-functional changes such as acute or chronic mortality. Such sublethal pollutant effects should be of major interest and concern to individuals formulating environmental policies and water quality criteria because many more aquatic organisms encounter sublethal rather than acutely or chronically lethal concentrations of pollutants in nature.
